Review Collection Cost Calculator

Know exactly what each review costs you — and whether your collection strategy is delivering positive ROI.

Every review on your store has a cost associated with it, whether it is the time spent on manual outreach, the subscription fee for your review app, the discount offered as an incentive, or the SMS credits used for post-purchase requests. Most merchants have no idea what their actual cost per review is, which makes it impossible to evaluate whether their review strategy is profitable.

This calculator breaks down your total review collection costs across all channels and divides by the number of reviews collected to give you a true cost-per-review figure. Combined with the revenue impact data from our Review ROI Calculator, you can determine whether each review is generating a positive return and identify which collection channels deliver the best economics.

How to Use

1

Enter your review app costs

Input your monthly subscription fee for your review collection app. Include any add-on costs for photo reviews, video reviews, or advanced features.

2

Add incentive costs

If you offer discounts or credits for reviews, enter the average incentive value and the percentage of reviewers who use it.

3

Include outreach costs

Add SMS credit costs, email platform fees allocated to review requests, and any staff time spent on manual review solicitation.

4

Enter reviews collected per month

Input how many reviews you collect monthly across all channels. The calculator computes your cost per review and compares it to the revenue each review generates.

Formula

Cost Per Review = (Monthly App Fee + Monthly Incentive Costs + Monthly Outreach Costs) / Monthly Reviews Collected. ROI Per Review = Annual Revenue Per Review - (Cost Per Review × 12). Break-even is reached when annual revenue per review exceeds annualized collection cost.

Interpreting Your Results

If your cost per review is under $5 and each review generates $20+ in annual revenue, your collection strategy is highly profitable. If cost per review exceeds $15, look for leaks — expensive incentives, low response rates, or underperforming channels are common culprits.

The key optimization is not necessarily reducing cost per review but maximizing the revenue each review generates once collected. Eevy AI focuses on exactly this: by genetically optimizing how reviews are displayed, each review works harder for your store, improving the ROI of your entire collection investment.
